A short bar magnet of magnetic moment 5*25xx10^-2JT^-1 is placed with its axis perpendicular to earth's field direction. At what distance from the centre of the magnet, is the resultant field inclined at 45^@ with earth's field on (i) its normal bisector, (ii) its axis? Magnitude of earth's field at the place 0*42G . Ignore the length of the magnet in comparison to the distances involved.

A short bar magnet moment 5.25 xx 10^(-2)JT^(-1) is placed with its axis perpendicular to the earth's field direction . At what distance from the centre of the magnet, the resultant field in inclind at 45^(@) with earth's field on (a) its normal bisector and (b) its axis . Magntiude of the earth's field at the place is given to be 0.42 G . Ignore the lenght of the magnet in comparison of the distance involved .

(i) A block is connected to an ideal spring on a horizontal frictionless surface. The block is pulled a short distance and released. Plot the variation of kinetic energy of the block vs the spring potential energy. (ii) A ball of mass 200 g is projected from the top of a building 20 m high. The projection speed is 10 m/s at an angle theta=sin^(-1)(3/5) from the horizontal. Sketch a graph of kinetic energy of the ball against height measured from the ground. Indicate the values of kinetic energy at the top and bottom of the building and at the highest point of the trajectory, specifying the heights on the graph. Neglect air resistance and take g = 10 m//s^(2)
